Specification of Letters Patent. j 15,1914;

Application filed .Tune 28, 1913. Serial No.'776,220.

To all w/zom'z't may concern Be it known that I, HENRY O. SMEAD, citizen of the United States, residing at Newton in the county of Harvey and State of Kansas, have invented certain new and use ful Improvements in- Lubricating Journal- Boxes, of which the following is a specification.

in lubricating journal boxes.

The primary object of the invention is'to provide a lubricating mechanism dlsposed within the journal box which will supply oil to the journal and which will continue to lubricate the journal after the supply of willbe resiliently supported in contact with. the journal and which may be conveniently renewed when the same becomes worn.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in'

which Figure 1 is a view showing a longitudinal sectional view of the box; Fig. 2 is a detail view of the lubricant supplying member, partially broken away to illustrate the interior construction of the same Fig. 3 is a section taken transversely through the box,

the upper portion of the box being broken 7 away; Fig. 4 is a top view showing the manner in which the terminals of the shaft on which the lubricant supplying roller is mounted are supported within their bearings; and Fig. 5 is an end elevationillustratingsaid mounting.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawing, 10 designates the journal box which is of the usual construction and which receives the journal 11 and the usual brass 12. Arranged in the base portion of the box adjacent each of its ends are supporting frames 13 and 14. These frames are substantially U-shaped and have their side portions 15 bolted to the sides of the box, their base portions being formed with.

This invention relates to animprovement flanges 16 which are bolted to "the base of the box. Each; of the frames is provided censtrally with vertically extending guide arms- 17 and 18'which are disposed in'spaced relation, forming the guides for supporting.

blocks 19. The faces 20 of the "armsar'e" slotted as at-21 to receivethe extensions 22" of the blocks, the blocks thus being support ed against endwise movement.' I

A shaft 23 is supported bythe blocks 22, the terminals of said shaft extending within the blocks. A spring 24is interposed'between the bases 25 off'the frames and the blocks 19, whereby the blocks Will normally be maintained in raised position. A roller 26 is mounted on the shaft 23. This roller is provided with a series of longitudinally disposed channels 27, there being a packing of waste, asbestos or any shredded fiber of an absorbent nature arranged in said channels, itbeing understood that the roller may be formed of metal, wood.or fiber. The roller throughout its length is provided with spaced rows of apertures 29. The roller is spaced from the base of the journal box and travels through the pool of oil, conveying the same to the journal and evenly distributing it throughout the length of the journal, it being understood that the oil is carried on the outer surface of the roller and supplied to the journal.

It will be noted that as the roller travels through the oil, oil will pass through the openings 29 and saturate the packing 28. The lubricant, which is supplied to the roller when the journal box is properly supplied with oil, is not fed from the packingbut directly from the pool. When the supply of oil becomes exhausted in the pool it will be seen that the oil will still be supplied to the journal, the oilrbeing fed from the packing through the apertures 29.

Thus even after the supply of oil in the.

journal box has been completely exhausted, the journal will be lubricated. tudinal channels 27 are closed at the ends of the roller by concave disks 30 which are mounted on the shaft 23, the disks preventing the oil with which the material 28 becomes saturated from passing out through the ends of the channels 27. The ends of the roller are convex, whereby the concave plates may snugly embrace the same and prevent the material 28 from moving longitudinally of the roller.

The many advantages of a construction The longiof this character will be clearly apparent,

as it Will be noted that it provides", when the lubricant compartment is partly filled with oil, means for distributingthe" same quantity of oil atone end of the roller as at the other endand atthecenter; It will also be noted that after the. supply of oil in the journal box has become'exhausted,

' the; journal will be lubricated by means contact with jthe'journal by means of the of the oil saturated material 28, and that the rollenwill. be constantly maintained .in

' springs .25, It-will also be seen that the structure is such .asgmaybe easily vand ec0-' nomically manufactured, and that it may begplaced within the journal box without-u altering its construction.

What Iclaim is: v a j ;;lubricating mechanism for-AV journal boxes;including a roller mounted in the journal box and adapted to; bev immersed co pijes of potent in be obtained for in a"1'ubri"cant contained in the journal box, saidroller being formed with an annular series of longitudinally extending channels comprehended within its periphery, and
